GRAIN CRIB.

Application led October 28. 1921. Serial Nq. 511,204.

To @ZZ whom t may concern:

Be it known that l, GEORGE B. READ, a citizen of the United States of America, residing at Bloomington, in the county of Mc- Lean and State 'of Illinois, have invented certain new and useful mprovements in` Grain Cribs, of which the following is a specification.

My invention relates to grain cribs.

My invention has special reference to a crib built in circular Jform and employing in its structure comparatively thin concrete staves, or sections, without using any plastic material, such staves being sustained and held in proper position and relation within the structure by means of hoops or bands.

The principal object of my invention is to provide a crib for housing both ear corn and small grain in a comparatively small circular crib built up of stave members.

The invention consists in the vcombination in a circular crib of a lower, or ear corn section, built up of ventilated stave lsections and an upper small grain section built up of solid staves, and associated Ventilating means to facilitate air circulating through the ear corn section, but notvthrough the upper or small grain section, although a ventilating stack for the ear corn section passes through vthe small grain bin. This Ventilating means, in passing through the small grain bin, is closed until itreaches practically the cupola oir the crib. ln the drawings, Fig. 1 shows a side elevation of the complete crib structure, with yparts broken away to show details of interior construction. F ig. 2 is a longitudinal sectional view of the crib. Fig. 3 is a detailed view of one of the stave sections having a supporting ledge integrally 'formed therewith.

My invention includes a special form of partition between the ear corn and small grain sections ot the crib, whereby a ready deflection of? the latter is facilitated to discharge points in the circumferential wall of the crib.

My invention further includes detailed matters of structure hereafter particularly pointed out in the claims.

1n the practical art relating to cribs and ,silos it has beenthe practice that when circular structures were to be built to be utilized as silos that solid blocks alone have been employed in developing such structures, and when developed rfor use to house ear corn, ventilated stave sections alone have vsheller drag.

bcenuemployed, -1n the structure herein eX- emplizied, 1 have developed a plan of utilizing a comparatively small circular structure, built up of stave sections, that will house and successfully preserve both ear corn and small grain.

Referring to the drawings :-10 is a concrete base or footing, 1()a are stave members, and 10? is a concrete floor provided with a transverse open way, 11 therein. 12 are cov-V ering sections t'or the top of said opening or way 11, the same being formed in sep arate sections, adapted to be removed, to facilitate the discharge of ear corn into the 13 is a door-way provided to facilitate entry into the lower portion ot' the ear corn section of the crib to 'facilitate initial discharge of corn therefrom. 111 refers generally to Ventilating stave sections. Built up over one side of a portion of the transverse open way 11, is an enlarged entry way 15, having its outer end communicating with a door 16, similar to the one shown at 13. This entry way has its upper and side portions ventilated in a manner similar to the Ventilating stack, to be described later. 18 is a Ventilating staclr which may be developed in any Yform desired, but as here shown, comprises relatively spaced vertically disposed framing members connected by short-board sections suitably spaced apart to permit free entry of air into the stack. rlhis Ventilating stack, as shown in Fig. 1, of the drawings, has only its lower portion ventilated and the upper section, or rather the section pass* ing through the small grain bin is closed for obvious reasons. 19 are floor or partition sections, shaped respectively to conform to the shape of the crib wall and inclined from a central transverse line through the crib body to, land in abutment with the interior face ot the crib wall, said partition members 19, being` supported at intermediate points loe-y tween the ridge and the wall, by transverse members 20, which have their ends supported upon the projecting ledges 21, on suitably positioned stave sections 22, as shown in Fig. 3 of the drawings. These stave sections 22, have the supporting or projecting ledge 21, integrally cast therewith and are specially formed fory this particular portion of the crib. Fig'. 2 of the drawings shows clearly the mounting of these staves. 23 are chute members constructed of any suitable'material and entered and secured in conformatory openings, in the crib wall and positioned,

their lower portions, in line with the floor or partition members 19, and at approximately the center point of the arc described by the outer edge of said-,floory or partition members, whereby grain deposited in the small grain sections of the crib will be grav,-

is housed, has its walls-formed by solid stave sections. At the peak of the roof oi the 'c'ribi structure, a super-imposed housing 25, may be provided, having the usual ventilating ways, 26, and, in this instance, also y openable window members 27, whereby entry of a grain elevating member may be made to facilitate discharge of small grain or ear corn into their respective compartments. The Ventilating stack 18, has

mounted, or rather hinged, therein, at anintermedate point thereon, hinged door members 28. These door members are located inthe Ventilating stack just beneath the floor or partit-ion members 19, and are hinged in such manner that when thrown outwardly, they form a' portion of the ventilating stack, but when in their inward position, closey the Ventilating stack, whereby'openings are left, for the ear corn to pass into the crib.

- Again at the top of ythe Ventilating section is shown door members 29 which may be thrown to an inward position to form a closure for the Ventilating stack, .or to an outward position, whereby the Ventilating stack acts as a means for transmitting the ear'cor'nv to the lower or corn'crib section,

To'more clearly bring out the functions of the door members, we may sa that it is the usual custom to project t e upper section of an outside elevator member into the openable windows 27, in the cupola, whereby either small grain or ear corn may be discharged thereinto. Should it be desirable to iill the corn crib, the upper door members 29, are opened, and the lower door members thrown to their inward, or closed position, with the result that ear corn discharged into the upper end ofthe ventilating stack, will strike against the lower door members and carom 0E into the corn crib. When the corn crib has been sufficiently filled, the door members 28, are thrown outwardly, forming a walled portion of the lVentilating stack, whereupon said stack is able to yfunction in its normal way.

When itis desired to fill the small grain section or bins, the upper door members 29,

are thrown in their inward or closed position Vand small grain is delivered by the outside elevator to the cupola, and caroms .o the closed doors into the grain bins. A wall portionl is shown at 30 in the small grain section, but this is not a necessity unless diiferent kinds of small grain are to be housed.v
